Cabbage haploid breeding method

The invention discloses a cabbage haploid breeding method, particularly a method for quickly breeding new cabbage variety, aiming at overcoming the defects that the traditional cabbage breeding method results in long process and low efficiency. The method utilizes the cabbage haploid culturing technology and the traditional male sterile line breeding technology to complete the quick breeding of the good and pure cabbage line. The method comprises the following steps of: preparing an explant, inducing the haploid, regenerating and culturing, transplanting to the field, doubling the chromosome, isolating and pollinating, sieving economic character, and subsequent breeding. The invention adopts the cabbage anther haploid breeding technology to breed and omits the insemination process, thereby avoiding generating heterozygous, simplifying the homozygous procedure of the heterozygous, greatly shortening the breeding period, and enhancing the breeding efficiency.
